Passing thought - would you place money on the giants siding with the Norse pantheon, or what? And if Ragnarok hasn't happened, there's the World Serpent to contend with as what I would deem a very major actor with no strict affiliations beyond "EAT TREE, DESTROY WORLD".

You don't have to schedule Apocalypse or Ragnarok at the same time as this particular clash, so there's also the interesting thought of asynchronous "end times" and all actors considering bringing about their own end time early in order to settle the issue in their factions favor.
